The article that Cindy referenced to the _British Trade Journal_, October 1, 1907, p. 377 titled "New Catalogues and Price Lists" is available on google book search and does make reference to the Gaumont company filming various pageants including Oxford and Mark Twain. I think it is likely that such a film was made. YouTube currently includes a number of films from 1897 of Queen Victoria's Jubilee (which Mark Twain attended) and they appear to be filmed from various camera angles. (Picking Clemens out of the crowd in those films would be a supreme challenge.) The fact that footage from 1897 still survives seems to offer hope that footage of the 1907 Oxford pageant may also survive. It does seem unusual that Clemens would make no reference to the filming in his autobiography. Was the film the historical reenactment of British history that he described in his autobiography or the awarding of his honorary degree, or scenes from both? However, another more pertinent question is whether or not the entry for the film on the IMDB website (which shows the company issued hundreds of films) was compiled from a printed catalog or whether it was compiled from some public or private archive of actual footage.
